As a data point: my company liberalized work from home to every employee a week before the first case was detected in our state, under the assumption that it was either already here and just hadn't been discovered in testing yet, or would be very shortly. When the first case was detected, the office was closed and work from home became mandatory at least through the beginning of April.
